だめ多くの問題があった。When conventional solar heat utilization systems target loads that fluctuate greatly depending on the season, such as hot water supply and air conditioning, there is usually a large surplus of heat outside of summer, and this is necessary to prevent the heat collecting medium from boiling. A large amount of excess heat must be removed. This meant that they had to consume large amounts of cold water and consume electricity by operating cooling towers. Furthermore, in the event of a power outage, these devices for discharging excess heat may damage the operating system. As described above, conventional excessive heat treatment and boiling prevention methods cannot control the incoming heat, but are intended to control the emitted heat, so there are many problems.
本発明の目的は、このような問題を解決した太陽熱利用
装置を提供することである。An object of the present invention is to provide a solar heat utilization device that solves these problems.

Reference numeral 2 denotes a first heat storage tank that receives the collected heat. A temperature sensor 3 that detects the temperature is inserted into the heat storage tank 2, and a signal from the temperature sensor 3 is input to a control box 4. , the shielding film winding device 6 is driven by the interlocking winding drive section 5. 7 is a device for winding up the shielding film using a mechanism such as a spring that does not require electricity. 8 is a heating/cooling load that varies greatly depending on the season, and 9 is a hot water supply load that can be expected to be approximately constant throughout the year. 10.10'.

ドリンク１３を持っていて集熱器１の架台に固定された
ガイドワイヤー１２にスライド自在に懸架されている。There are two ways to divide the blocks of the heat collector assembly: as shown in Figure 1, there are two ways to divide the blocks: A, B, and C; and A'.
, B', and C' may be considered, but in FIGS. 2 and 3, the method of dividing by columns is shown based on the former method. The solar radiation shielding film 11 has guide links 13 at the corners of its ends, and is slidably suspended on a guide wire 12 fixed to the frame of the heat collector 1.

にハネに巻き込みの力を貯えることによって動作する。Reference numeral 14 is a lead-in wire fixed to the lower end of the solar shielding film 11 and pulled down, and is connected to the winding device 7. The shielding film winding device 6 is electrically operated, and the winding device 7 does not require power, but operates by storing winding force in a spring during winding operation.

４図および第５図に示された制御フローチャートおよび
動作状態図に基づいて説明する。Next, the operation of the solar heat utilization device configured as described above will be explained based on the control flowchart and operation state diagram shown in FIGS. 4 and 5.
通常の集熱状態では日射遮へい膜１１が巻き上げられて
いる。集熱時に温度検知体３の検出温度が設定値９０℃
以上（この温度はシステムによって変る）になると第１

を遮へいする。In a normal heat collecting state, the solar radiation shielding film 11 is rolled up. During heat collection, the detected temperature of the temperature sensor 3 is set at 90°C.
If the temperature exceeds (this temperature varies depending on the system), the first
One of the stages (C or C' in FIG. 5) of the heat collector blocks divided into stages K is shielded from solar radiation. When the temperature rises further to 90° C. or higher, the second stage is to shield the two heat collector blocks (B and C or B' and C' in FIG. 5) from sunlight.
その状態でも９０℃以上になれば、熱のうけ入れを必要

全集熱器ブロック（第５図でＡ、 Ｂ、 Ｃ又はＡ’、

電時は第３段階と同じく全集熱器ブロックが遮へいされ
る。Even in that state, if the temperature reaches 90°C or higher, there is no need to accept heat. In other words, it is determined that there is no load, and the third step is to remove all the heat collector blocks (A, B, C or A' in Figure 5).
B', C'). In the stepwise operation, if the temperature detected by the temperature sensor 3 is between 85.degree. C. and 90.degree. C., the state of each step is maintained. Also, in the event of a power outage, all heat collector blocks are shielded as in the third stage.
実施例では第１の蓄熱槽の温度により日射遮へいの動作

た上中下の段で集熱器の集合体を分割する場合は、６と
７の上下位置が逆になる。In the embodiment, the operation of solar radiation shielding is controlled by the temperature of the first heat storage tank, but this is because the heat storage tank has a large heat capacity, so the frequency of shielding operation can be reduced. It is also possible to control the outlet temperature. Furthermore, when dividing the heat collector assembly into upper, middle, and lower stages, the vertical positions of 6 and 7 are reversed.

われる。The structure and operation of the present invention have been explained above, and its effects are as follows: In conventional boiling prevention systems, water and electricity are wasted as the heat is discarded. The method of limiting heat does not consume water or electricity, and in the event of a power outage, the conventional method could not prevent boiling unless the control mechanism was activated, but with the present invention, the shielding operation does not require power. Preventing boiling is very simple.
